Abstract

PURPOSE:To make it possible to allow the title mechanism to dot in an arbitrary sequence by performing the selection of a pen tip and the dotting operation by using one motor whose small gear is fixed to an output shaft so that the motor can be rotated in the forward and reverse directions, a one-way clutch for transmitting rotation, a cam and a roller in symmetry which are coupled with a rotary shaft and reach the highest point at the rotary angle of 180 degrees. CONSTITUTION:When an ink containing part 8 is rotated in the counterclockwise direction through a gear 7 by the clockwise rotation of an intermediate gear 5, a pen-tip part 9 is also rotated by the same rotary angle of the ink containing part 8 at the same time by a bevel gear 12B which is engaged with a bevel gear 12A. The tip of the pen tip 9a is applied to ink 14 which is impregnated in a porous body through the ink feeding port at the bottom surface of an ink containing part 9. Thus the ink is supplied. Then, the motor 1 is rotated in the reverse direction. A main shaft 3 is rotated in the counterclockwise direction through a large gear 2. Only a one-way spring clutch 4B using a counterclockwise tightly-attached coil spring is rotated, and the rotation is transmitted. Thus, a cam 6 is rotated in the counterclockwise direction. When the cam 6 is rotated by 180 degrees, a roller 11 reaches the lowest point of the cam. When the roller 11 rises up, a shaft 15 which supports the roller 11 is rotated with a rotary supporting point 10 as the center. The pen tip part 9 at the other end of the shaft 15 is lowered. Thus, the pen tip 9a dots on recording paper 13.

(Function) In the pen dotting mechanism of the present invention, the roller contacts the highest point of the cam, the shaft supporting this roller remains horizontal, and the bevel gear fixed to the shaft is placed on the bottom of the ink storage section. While meshing with the fixed bevel gear, the motor is rotated in a direction in which the rotation of the main shaft is transmitted to the shaft of the intermediate gear via the one-way clutch. Then, the intermediate gear rotates, the gear meshing with it also rotates, and the ink storage section fixed coaxially with this gear rotates. Then, the pen tip rotates at the same time by the bevel gear that meshes with the bevel gear coaxially fixed to the bottom of the ink storage, and the tip of the pen hits the porous body through the ink supply port on the bottom of the ink storage to supply ink. supply. The rotation angle of the pen tip part can be set arbitrarily, and the pen tip stops when the pen tip to make a dot comes to the bottom and faces the recording paper. Next, when the motor is rotated in the opposite direction, rotation is transmitted to the camshaft by the other one-way clutch, causing the cam to rotate. Then, the roller rolls without contacting the cam surface, and when the cam rotates 180 degrees, the roller reaches its lowest point, and as the roller rises, the shaft that supports the roller rotates around the pivot point. The pen tip at the other end of the shaft moves down and the pen tip makes a dot on the recording paper. Furthermore, if the motor is stopped when the cam has rotated 180 degrees, the roller will be located at the highest point on the cam surface, one dotting operation will be completed, and the bevel gears will return to the meshed state. Thereafter, by repeating the above-described series of sequential operations, dotting operations are sequentially performed using each pen tip.

This will be explained with reference to (b) and (c). Figure 2 (
In the spring clutch shown in a), the shaft (21) and the gear (22) are such that the small diameter portion (21a) of the shaft (21) is rotatably fitted into the boss (22a) of the gear (22). The shaft (21) and the boss (22a) are made to have the same outer diameter. And the shaft (21)
and the boss (22) of the coil spring (23) and the gear (22).

Assuming that the tight coil spring (23) is an Ishinomaki (see Fig. 2 (b)), the gear (22) is fixed and the shaft (21
) counterclockwise, the tight coil spring (23
) also tries to rotate in the same direction, but the gear (22) is fixed and does not rotate, so the tight coil spring (23) twists and tightens the shaft (21) and boss (22a), and the gear (22) It tries to rotate together with the shaft (21). When the shaft (21) is rotated clockwise in the opposite direction from the previous rotation, the tight coil spring (23) is twisted in the direction of expansion, increasing its inner diameter, and the rotation is not transmitted to the gear (22).

If the close coil spring (23) is left-handed (see Fig. 2 (C)), when the shaft (21) is rotated counterclockwise, the close coil spring (23) will twist in the direction of expansion and the inner diameter will increase. When the shaft (21) is rotated clockwise without the rotation being transmitted to the gear (22), the tight coil spring (23) is twisted in the direction of decreasing the inner diameter and the shaft (21) is rotated clockwise.
21) and the boss (Z2a), the gear (22) tries to rotate together with the shaft (21). In this way, by using close-contact coil springs with right-handed and left-handed winding directions, we have created a unidirectional spring that transmits or does not transmit rotation to the driven side in the opposite direction when the rotation direction of the driving shaft is forward or reverse. You can get a clutch respectively.

Only B) transmits rotation and cam 0 rotates counterclockwise. Then, the roller (11) rolls without contacting the cam surface, and when cam 0 rotates 180 degrees, the roller (11) reaches the lowest point of the cam, and the roller (11) rises. The supported shaft (15) is the rotation fulcrum (10
), the pen tip portion 0 at the other end of the shaft (15) is lowered, and the pen tip (9a) makes a dot on the recording paper (13). Furthermore, if the motor is stopped when the cam ■ has rotated 180 degrees, the roller (11) will be located at the highest point on the cam surface and one dotting operation will be completed, and the bevel gear (12A) and (12B) return to the engaged state. Thereafter, by repeating the above-described series of sequential operations, dotting operations are sequentially performed using each pen tip (9a).

According to the pen dotting mechanism of one embodiment of the present invention, a single motor can perform pen tip selection and dotting operation, and space within the recorder can be saved, leading to cost reduction and miniaturization and weight reduction. Further, since the rotation of the pen tip section can be set to any angle, the order of the pens for dotting can be arbitrarily selected.

As described in detail above, according to the present invention, one motor capable of forward and reverse rotation is used, and the rotation of the main shaft rotated by this motor is transferred to each motor whose rotating direction on the main drive side is opposite when transmitting the rotation. Via a directional clutch, one side is transmitted to a drive system that rotates the pen tip to select the color of the pen tip, and the other is transmitted to a drive system that moves the pen tip up and down to make dots on recording paper with the selected pen tip. By realizing a pen dotting mechanism that selects a pen tip and makes dots using the pen tip by rotating the motor forward and reverse in chronological order, only one motor is required for the dotting mechanism, and the recorder can It also saves space inside, leading to lower costs and smaller size and weight. Furthermore, since the pen tip portion can be rotated at any angle, the order in which the pens make dots can be arbitrarily selected.
